The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’re looking at a solid run of surf at Jaconé, but it’s a bit of a slow starter. The first couple of days are pretty flat and ordinary, so you’re not missing much if you sit those out. The real action kicks off Wednesday morning, August 5th, when the swell bumps up and conditions start to clean up nicely.
The standout window is Sunday, August 9th. That’s the day. Morning sees a 7ft swell from the SSW, with a long 14-second period, and the wind is light offshore from the NE. The combined energy is a hefty 1616, so there’s plenty of power in the water. This is proper groundswell, and with that direction and period, it’s going to unload cleanly on the exposed points. The afternoon goes glassy with a light SSE breeze, holding the swell at 6ft. This is excellent surf, but at this size, it’s best left for experienced surfers. The water temp is pretty much where you’d expect for this time of year, nothing unusual.
The week after that keeps things interesting. Thursday, August 13th, serves up a clean morning with a 5ft S swell at 10 seconds, light offshore NE wind, and moderate energy (559). Friday, August 14th, is another cracker – the afternoon session brings a 6ft S swell with a 15-second period, combined energy of 1434, and a gentle cross-offshore breeze. That’s long-period groundswell, so expect clean, powerful lines at the reefs and points, though it might be a bit too lined-up for the beach breaks.
There’s a bit of a rough patch around the 15th and 16th, with cross-onshore winds and choppy conditions, so steer clear of those days. The 18th is marginal, but Tuesday the 19th morning sees a return of clean, offshore wind from the NE, with a 4ft S swell, so it’s worth a look if you’re keen for a smaller session.
Overall, the best bet is hands down Sunday, August 9th – that’s the one to circle on the calendar. For a solid second option, Friday the 14th afternoon is also a beauty. The rest of the run has good moments, but those two are the standouts.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
